Specification forming part of Letters Patent No. 174,953, dated March 21, 1876; application filed February 11, 1876.

devices for containing and delivering kerosene.

oil, for the purpose of filling lamps or other vessels, such devices consisting, essentially, of a can or vessel for containing illuminating fluid; a superdisposed box or chamber for temporarily receiving the lamp or other vessel to be filled a discharge pipe for conducting the fluid to said lamp or vessel and, lastly, of a suitable pump connected with or forming part of such discharge-pipe, and situated within the oil can or reservoir, but operated from the upper receiver, the whole constituting a device for enabling lamps to be filled with safety, and avoiding the disagreeable consequences common to the ordinary method of storing and using kerosene-oil in families, stores, factories, 8E0.

The drawings accompanying this specification represent, in Figure 1, a plan with the cover removed, and in Fig. 2 a vertical section, of a device containing my improvements.

In these drawings, A represents a can or vessel for containing kerosene or other highly inflammable illuminating fluids, this can or vessel being cylindrical, square, or oblong, or of any proper form, and provided with a suitable cover, B. Within the upper part of the vessel A, I place a horizontal shelf or partition, 0, which divides such vessel into two portions, (1 b, the lower one, 12, serving tocontain a supply of illuminating fluid, and the upper one, a, constituting a temporary receptacle for the lamp or other vessel to be filled, a waste port or outlet, 0, being created in the partition 0, through which oil spilled or otherwise escaping into the receiver a may flow directly back into the reservoir b. D, in the accompanying drawings, represents an upright force-pump, disposed within the lower chamber or oil-reservoir b, the handle or rod of such pump extending upward through the floor or partition 0, in order that access may be readily had to it. Disposed alongside the pump D, and, like it, situated within the lower chamber 11, is an upright tube, d, which projects through, and, preferably, somewhat above, the floor C, but is closed against any communication with the said chamber b, except through the pump D, above the lower box or valve f of the latter. The lower end of the pump D connects with the interior of the tube 01 by a valve-port and valve, as shown at g,- consequently oil raised by the pump D from the chamber b is driven upward, through the tube (1, toward the receiving-chamber or inclosure a.

Heretoi'ore, in devices of this character, the tube (1 extends permanently above the floor O to such a height as to enable a lamp, or other vessel to be filled, to be placed below its outlet. This necessitates a bulky and clumsy structure, which my present improvement is intended to avoid, and, in carrying said improvement into practice, I stop the tube d at or near the floor G, and employ in connection with it a second tube or conductor,'h, which is disposed within it, as shown in the drawings, the lower end of this auxiliary or extension tube h being of a size to tightly fill the upper end of the tube d, and maintain itself in position when raised to its highest point.

In the use of the apparatus above described, a lamp or other vessel to be replenished with oil from the reservoir b is placed upon the floor O, and closely adjacent to or below the discharge -nozzle '1 of the movable extensiontube h. The tube h is now raised to its highest point, where it maintains itself by friction within the tube (1, care being taken that the nozzle i is placed immediately over the fillingorifice of the lamp or the mouth of the "essel to be filled. By means of the pump D, oil is forced from the reservoir 1) upward through the tube d h, and is discharged into the lamp or vessel until the latter has received the destined supply.

By means of the extension-tube h, I am enabled to greatly reduce the heightaud cost of the vessel or structure, which, for domestic uses, are matters of importance, as is also the fact that the device occupies less space.

I do not confine the construction of my device to the sunken receiver or inclosure a, as the walls which bound this inclosure may be dispensed with, and the floor C be depressed at or near its center, or some other suitable point, to arrest oil accidentally spilled or escaping from the tube h. Nor do I confine myself to the means herein shown for prolonging or contracting the tube at by disposing the extension it within it, as this extension may be made to slip over the top of said tube 01,

or may be hinged to such top or otherwise combined with it.

I claim- The oil-receiving structure or cabinet herein explained, consisting of the vessel A, with its chambers a I), the pump 1), and extensiontube d h, substantially as and for purposes stated.

THEODORE L. HARLOW.
